I asked Chuck the same question, here is his response:
'I've never tried it that way, but it appears it works. If I plug in some
test numbers for Nitrate in KNO3, in a 50g tank, 1 Tablespoon in 500ml
of water, each ml added to the tank adds 0.04ppm. If I were to
dump the entire 500ml bottle in, that would be 0.04 x 500, which gives
me 20ppm. And if I use your method of plugging in 1ml, I get 18.84,
which is the same when you factor in rounding losses...'
